minimalinvasiver

Minimalinvasiver, commonly referred to in English as minimally invasive, describes medical procedures designed to reduce tissue disruption, pain, and recovery time compared with traditional open techniques. These procedures typically use small incisions, natural orifices, or both, and employ specialized instruments, endoscopes, cameras, and imaging guidance to access internal organs and perform diagnostic or therapeutic tasks.

Techniques include laparoscopy for abdominal and pelvic operations; thoracoscopy for chest procedures; endoscopy for visualization and intervention via mouth or anus; interventional radiology with percutaneous catheters and image guidance; robotic-assisted surgery that enhances precision and maneuverability; and NOTES, natural orifice translumenal endoscopic surgery, for transoral or transgastric access.

Benefits commonly include reduced blood loss, less postoperative pain, shorter hospital stays, and faster return to normal activities. Limitations and risks involve limited access for certain diseases, longer operative times during learning curves, potential injury to surrounding structures, selective suitability for patients, and higher upfront equipment costs that may be offset by downstream savings. Not all procedures can be performed minimally invasively, and careful patient selection remains essential.

Historically, laparoscopy emerged in the late 20th century and rapidly expanded across general surgery, gynecology, and urology. Today, minimally invasive techniques are applied in many fields, with ongoing research into single-incision approaches, improved imaging, and the expansion of robotic systems and NOTES. The scope continues to broaden as technology and training advance, while some procedures still require traditional open methods.
